JPS5529288A - Permanent magnet rotary machine - Google Patents

Abstract

PURPOSE: To provide a permanent magnet rotary machine which permanently rotates by setting a special relation between the stator and rotor positions of magnets having particularly high magnetic characteristics in one direction and magnetic flux direction and mounting to repel to each other.

CONSTITUTION: Stator 1 and rotor 2 of magnets having particularly high magnetic characteristics in one direction are arranged to face the same magnetic poles oppositely to repel each other. The stator 1 and rotor 2 are so disposed at the centers 9 and 10, respectively of the circular arcs of the peripheral surface operated with the respective stator 1 and rotor 2 at the points to equally divide the circumferences 7 and 5, respectively in a manner that the stator 1 has 0∼90° at the rotor side with respect to the tangential line 11 of the rotating direction from the center point 9 of the peripheral surface and the rotor 2 has 0∼90° at the stator side with respect to the tangential line 12 of the counterrotating direction from the center point 10 of the peripheral surface in the magnetic flux ranges C and D, respectively. Thus, the rotor is mounted in suitable air gap oppositely to the stator via a rotary shaft 4 to thereby provide permanently rotating motion.
